Integrates seamlessly into established cannulation techniques, allowing clinicians to maintain familiar procedures while adding an additional layer of protection during hemodialysis.
A built-in foot plate remains closed during normal treatment conditions.
If the needle dislodges, the foot plate springs open automatically.
The open foot plate obstructs blood flow pathway, causing a sharp rise in venous pressure.
The dialysis machine detects the abnormal pressure and activates its alarm safety algorithm, stopping the blood pump.
This mechanical-to-machine communication creates a powerful added layer of protection.
Venous needle dislodgement (VND) is one of the most serious risks in dialysis treatment. The JMS CAVEO® Safety Fistula Needle is the first AV fistula needle designed with an integrated passive protection mechanism that helps trigger rapid dialysis machine pump shutoff in the event of dislodgement.
Engineered for safety, precision, and clinical efficiency, CAVEO® enhances hemodialysis protection without changing your established workflow.

The CAVEO® is an advanced AV fistula needle for hemodialysis featuring a patented integrated foot plate mechanism. If venous needle dislodgement occurs during treatment, the footplate opens immediately, obstructing blood flow pathway and creating a rapid pressure increase within the venous line.
This rapid pressure change is detected by the dialysis machine’s alarm monitoring system, prompting an automatic blood pump shutdown within seconds.
Early detection and rapid response to venous needle dislodgement may help reduce the risk of severe blood loss and often devastating complications.
